Description

Technical Field

[0001] The utility model belongs to the technical field of bone density ultrasonic measurement auxiliary, and particularly relates to a bone density ultrasonic measurement auxiliary device. Background Art

[0002] In the prior art, most of them adopt Figure 1 Bone density is measured in the manner shown: when using the ultrasonic bone density probe 10 to measure the radial bone density, the arm of the person being measured is placed on the table. Because this measurement method has no constraints, on the one hand, the hands of the person being measured are prone to shaking, and the ultrasonic bone density probe cannot accurately find the position of the radius, which affects the detection speed and accuracy; on the other hand, the arm has various postures, and the instrument operator needs to tell the person being measured how to place his arm each time, so that the radius faces upward for easy measurement. Each person being measured must correct the posture, which affects the efficiency of the measurement work. In addition, during the measurement process, the instrument operator holds the ultrasonic bone density probe in his hand, and the sensor part is close to the skin at the position of the radius of the person being measured. The wrist of the instrument operator is suspended in the air, making it difficult to maintain stability, and the wrist is prone to fatigue after long-term operation, making it difficult to cope with continuous measurement work.

[0003] After searching, the cited publication number is CN208287017U, the publication date is 2018-12-28, and the name is a bone density auxiliary measurement device, including a base plate, a first handle, a second handle, a first support plate and a second support plate. The first handle is used for the right hand of the person being measured to grasp, and the second handle is used for the left hand of the person being measured to grasp, and the second handle is opposite to the first handle. The second support plate is opposite to the first support plate. The first handle, the second handle, the first support plate and the second support plate are all arranged on the base plate, and there is a first spacing between the first handle and the second handle for the palm of the person being measured to be placed longitudinally, and there is a second spacing between the first handle and the second handle for the arm of the person being measured to be placed longitudinally. The above embodiment provides a bone density auxiliary measurement device, and the utility model can fix the arm of the person being measured so that the ultrasonic bone density probe can detect the radius, and can avoid wrist fatigue of the instrument operator, improve the stability of the instrument operator holding the ultrasonic bone density probe, and prevent the instrument operator's hand from shaking.

[0004] The above embodiment still has the following defects:

[0005] The above embodiment cannot fix the arms of the subjects with different arm circumferences when used. When the size of the device does not meet the requirements, manual adjustment is required, which increases labor intensity and reduces work efficiency. Utility Model Content
